[Alveolar anesthesia]

Area of Science:

• Dentistry
• Anesthesiology
• Oral Surgery

Context:

• Loco-regional anesthesia techniques are crucial for effective dental procedures.
• The posterior maxillary region presents unique anatomical challenges for anesthesia.
• Tuberosity anesthesia offers a specific approach to target superoposterior alveolar nerves.

Purpose:

• To describe the technique, indications, and contraindications of tuberosity anesthesia.
• To highlight the advantages of tuberosity anesthesia for posterior maxillary surgery and molar treatments.
• To differentiate tuberosity anesthesia from alternative methods in specific clinical scenarios.

Summary:

• Tuberosity anesthesia involves a direct anteroexternal approach to the maxillary tuberosity for single-injection loco-regional anesthesia.
• It effectively anesthetizes the superoposterior alveolar nerves, covering molars, buccal mucosa, and sinus structures.
• The procedure is well-tolerated, virtually painless, and rapid-acting, making it suitable for various dental treatments like crown preparations and pulpectomies.

Impact:

• Tuberosity anesthesia is the preferred method for posterior maxillary surgery due to its efficacy and patient tolerance.
• It expands treatment possibilities for upper molars, including complex restorative and endodontic procedures.
• Understanding its contraindications, such as vascular or hematologic disorders, ensures patient safety and guides the selection of alternative anesthetic techniques.
